Coastal plain deposits of the Gaza Strip have been distinguished in the Gaza Formation (Pleistocene) of the Kurkar Group. The Kurkar layers (medium to coarse-grained calcareous sandstone) are characterized by abundant crossbedding that has two sets of cross-beds. These Kurkar layers form the ridges along the Mediterranean coast. The dip, and dip direction of the cross-beds, were measured at fi ve sites to determine the palaeowind direction. The palaeowind directions were measured for the fi rst time in the study area. The Kurkar layers are interpreted as having been deposited in an aeolian environment. Results at Sheikh Ejlin Ridge show that the lower set is dipping eastward (19/099), while the upper set dips northeast (23/051). At the Al Montar Ridge however, the lower set dips southeast (18/146), while the upper set dips north (19/001). These ridges are not coeval, but the precise age relationship between them is as yet unknown. However, the results indicate that there was a change in the palaeowind direction during deposition of the Kurkar layers, from westerly to southwesterly at the Sheikh Ejlin Ridge and from northwesterly to southerly at Al Montar Ridge.

The current study documents for the first time the existence of four suites of dykes intruded the Neoproterozoic crustal rocks in southwestern Jordan. The oldest suite strike E-W followed by suites strike NE-SW, N-S and NW-SE which is the youngest one. Remote sensing and GIS techniques were used for mapping the dykes observed at the satellite image of the study area. Landsat Thematic Mapper color composite scenes allowed mapping of most the dyke swarms in the study area. Digital image processing technique was performed to map the dyke swarms in the study area. The emplacement of the dykes is consistent with extensional continental tectonic setting during the Precambrian time and before the deposition of the Cambrian sediments. The study gives an evidence for an anticlockwise rotation of the extensional stress regimes that caused these suites of dykes. Remote sensing and GIS technique used here could thus guide the interpretation and provide exact and accurate dyke mapping tools.
